Ali Hazelwood is the writing name of an Italian author and professor who lives in the United States. She writes romance novels and teaches neuroscience. Many of her books focus on women working in science, technology, engineering, and math fields, as well as in schools and universities.

Career
Hazelwood's first novel, The Love Hypothesis, was published in September 2021. It was on the New York Times Best Seller list for over 40 weeks. The story was originally written as a fan fiction story about Rey and Kylo Ren from Star Wars, which Hazelwood first posted on Archive of Our Own in 2018. In 2020, a literary agent contacted Hazelwood about the story and helped her prepare it for publication.
In 2022, Hazelwood published her second full-length novel, Love on the Brain, as well as three novellas: Under One Roof, Stuck with You, and Below Zero. In 2023, Hazelwood combined her three novellas into a book titled Loathe to Love You. That same year, she released her third adult novel, Love, Theoretically, and her first young adult novel, Check & Mate. In 2024, she released the paranormal romance Bride. Her seventh book, Not in Love, was published in June 2024. Deep End came out in early 2025, followed by Problematic Summer Romance, a spin-off of Not in Love. In October 2025, Hazelwood released her second paranormal romance novel, Mate.
